The paper “Evaluating Spread of ‘Gasless Send’ in Ethereum Smart Contracts” by David Prechtel, Tobias Groß and Tilo Müller received the Best Paper Award at this year’s Workshop on Blockchains and Smart Contracts (BSC). The award was handed over during the workshop which was held on June 24 to 26, 2019 in Maspalomas, Canary Islands, Spain. The paper presents an approach for analyzing Ethereum smart contract regarding to the issue of ‘gasless send’. Our analysis of 167,698 smart contracts currently deployed to the live Ethereum network shows that a total of 96.3 thousand (or 57%) might be affected by the issue of ‘gasless send’.
